base frame. Place the filters and fan boxes, taking great care to place them back in the
column they came from. Reference filter and fan box labels applied during their initial
installation. For more information on how to install the filtration technology, see
Step 8
Once all filters and fan boxes are installed, all connections are verified, and no units are
out of their original order, connect the filtered hood to power. Power up and check all
lights and fans for proper function. If the filtered hood is in alarm, check eGuard for the
explanation. If eGuard says the base frame has been replaced, press the
[mute]
button
on the command module. If the alarm is anything other than a replaced message,
disconnect the power, re-check all electrical connections and try again. Do not leave the
filtered hood running while troubleshooting.
When properly working, reinstall the front panel and resume using the filtered hood.
Neutrodine Filter Replacement
Filters are found above the base frame and above the fan box of the filtered hood. The
primary filte
r (should be labeled with a ‘P’) is the filter between the base frame and the
fan box. The secondary filter (should be labeled with an
‘S’) is the filter above the fan
box.
The primary filters must be replaced if:
1. One of the embedded sensors (standard molecode S or optional molecode A or
F) detects the presence of chemicals between the primary and secondary filters.
When this occurs, a filter replacement alarm is activated and displayed on the
command module and through eGuard.
2. Or the primary filters have been used for 36 months.
